MEDA: Measurement-Efficient Disorder-Aware Majorana Zero Mode Detection in Realistic Devices
Nathan Jones, Binayyak Roy, Valentine Mohaugen +4
The paper introduces MEDA, a framework that uses sparse, experimentally accessible measurements to detect Majorana zero modes in disordered quantum devices by mapping them to a rob…
Chiral Anomaly Induced Transverse Planar Transport Phenomena in Three Dimensional Spin-Orbit Coupled Metals
Rishi G. Gopalakrishnan, Binayyak B. Roy, Gargee Sharma +1
We investigate linear and nonlinear transverse planar transport phenomena (viz. linear and nonlinear Hall and Nernst coefficients) induced by chiral anomaly in three-dimensional sp…
Floquet-Engineered Parity Anomaly Staircase in a Cold Atom Dirac Lattice
Binayyak Roy, Vito Scarola, Sumanta Tewari
We propose a Floquet-engineered cold atom realization of a parity anomaly inspired anomalous Hall staircase in a two dimensional -flux lattice. The effective model hosts massiv…
Quantum Inductance as a Phase-Sensitive Probe of Fermion Parity Switching in Majorana Nanowires
Binayyak B. Roy, Jay D. Sau, Sumanta Tewari
We study the flux-dependent quantum inductance of a one-dimensional (1D) semiconductor-superconductor (SM-SC) Majorana nanowire coupled to a quantum dot in an interferometric setup…
Pfaffian-based topological invariants for one dimensional semiconductor-superconductor heterostructures
Binayyak B. Roy, William B. Cason, Nimish Sharma +1
We review the Pfaffian-based topological invariants in one dimensional semiconductor-superconductor (SM-SC) nanowire heterostructures and clarify their validity in f…
Topological invariant for finite systems in the presence of disorder
Robert Eissele, Binayyak B. Roy, Sumanta Tewari +1
Topological invariants, rigorously defined only in the thermodynamic limit, have been generalized to topological indicators applicable to finite-size disordered systems. However, i…
